Available in black, white or red, the Sony can be plugged into the mains where it will act as a charging dock. It also has an internal rechargeable battery for use on the go. Up to 5 hours of playback can be enjoyed from a single charge, but the 13W audio output drops to 4W when running off its battery. You can skip backwards or forwards through tracks, pause songs and adjust the volume via the bundled remote control. A second volume control is found on the speaker itself, along with an audio-in port that enables other devices to be connected to the speaker. The Sony RDP-V20iP Circle Sound iPhone speaker is priced at £150 inc VAT.
